Ronski's Solar & battery DIY build with whole house backup

Ooops!

We've all been there, see bigmike20vt's post today in the EV thread.

I've got mine programmed to charge in all IO periods and it will not discharge once charging is complete so I'm fully on grid during cheap hours. Is that the way forward?
 
I used to have my system set to charge in the 12:30 to 5:30 slot using Victrons built in charging, but it would charge at maximum power of 8kW, I thought it better to do it more gradual, so I just set my free electric schedule at a lower rate, but it doesn't take into account house load.

Its easy enough to modify, its basically the reverse of my discharge algorithm where I want to discharge to 15% SOC charge by midnight, instead I want to reach 100% by 05:00, and allow 30 minutes to balance the cells.

Just need to get around to adjusting the code.

I'll take a look at what bigmike20vt did.

I get the want for an integrated charger but it doesn't really matter. You can pole the Octopus API in NodeRed can't you? If so, you can trigger the battery to charge on the Octopus dispatching entity.

Could you give me a pointer where to find information on this dispatching entity please? Been having a Google and its a bit information overload. Does the dispatcher entity show when a cheap slot is on normal Go (00:30 to 05:30) as well?

Ideally I'd like to learn how to do this in Node Red on the Victron system, but I could use HA and use that to get the information to the Victron system. Also been trying to find out how to current the current kWh price from the API, but no joy.
